who seems not to be capable of saying anything without appending n shit to it n shit. Most notably a problem when attending important social functions like funerals and weddings n shit.

'n shit is a better way of finishing a sentence that you'd rather not drag out and continue. it is inserted at the end of a sentence or phrase. some people say 'and stuff' but saying 'n shit is clearly better. when having a conversation with someone you must insert the word 'n shit as many times as you can. infact, its almost a game too.
